我们正在开发一种自治的分布式存储系统，以有效地利用网络化的异构存储设备。它不是根据存储设备的静态性能指标，而是根据运行过程中测量到的有效性能值来动态配置存储层。根据数据块的读写趋势，将数据块转移到更合适的存储层。在之前的文章中，存储层是使用静态定义的阈值来设置的，但在本文中，我们提出了一种自适应设置阈值的方法。这种方法消除了根据运行时环境调整阈值设置的运行时参数的需要。它还得到了改进，以便可以为单个存储设置适当的参数值，而不是将单个参数值应用于整个系统。在以前的系统中，管理员必须定期重新调整参数值，以匹配存储设备的使用状态和进程的行为。然而，在本文提出的方法中，在操作过程中对参数值进行了微调，以减少管理员的工作量。仿真结果表明，与静态配置最优参数的方法相比，该方法的执行时间最多可减少30%左右。
We are developing an autonomous distributed storage system to make effective use of networked heterogeneous storage devices. It dynamically configures the storage tiers using effective performance values measured during operation, rather than static performance indicators of the storage device. Data blocks are transferred to a more appropriate storage tier according to their read/write tendencies. In the previous paper, the storage tiers were set using statically defined thresholds, but in this paper, we propose a method to set the thresholds adaptively. This method eliminates the need to adjust the runtime parameters for threshold setting according to the runtime environment. It has also been improved so that appropriate parameter values can be set for individual storage, rather than applying a single parameter value to the entire system. In the previous system, the administrator had to readjust the parameter values periodically to match the usage status of the storage device and the behavior of the process. However, in the proposed method, the parameter values are fine-tuned during operation to reduce the workload of the administrator. The simulation results show that the proposed method can reduce the execution time by up to about 30% compared to the previous method with optimum parameters configured statically.
